Abstract
A measuring and control apparatus for internal grinding machines with resting shoes for cooperating with the outer surface of a workpiece, including a control device for controlling the displacement of the grinding wheel relative to the workpiece, with devices for measuring the displacements; and measuring devices for carrying out measurements of linear dimensions of the workpiece, the devices means for measuring dimensions of the workpiece including a first measuring device adapted to provide a signal responsive to the value of the diameter of said outer surface of the workpiece. The control device is connected to the device for measuring the dimensions of the workpiece for receiving the signal from the measuring device and for controlling the displacement of the grinding wheel relative to the workpiece depending on the signal itself, for the grinding of an inner surface of the workpiece concentric with said outer surface.
